Delay When Saving Word 7.0 File to Windows NT 4.0 Server

 Last reviewed: March 13, 1998
Article ID: Q163525
The information in this article applies to:
  • Microsoft Windows NT Workstation versions 3.51 and 4.0
  • Microsoft Windows NT Server version 3.51 and 4.0

SYMPTOMS

In Microsoft Word version 7.0, there may be a delay when you save a modified document to a network drive that is located on a Windows NT 4.0 server.

CAUSE

The Windows NT client was ignoring the oplock break request from the server.

RESOLUTION

This problem has been identified as a Windows NT environment issue.

To work around this problem, you can disable an optimization called oplock (opportunistic lock) on the remote Windows NT server or you can apply the latest service pack.

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

  1. Start the Registry Editor (Regedt32.exe).

  2. Find the following key: 

          \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

             \LanmanServer\Parameters


  3. Add the following entry, if it is not already present:

    

          Value Name: EnableOplocks
      Data Type:  REG_DWORD

          Data:       0

   If the entry already exists, set the data to 0.


  4. Exit the registry.


  5. Shut down and restart Windows NT.
